The game is similar to Among Us, mixed with a game of pass the bomb. One player is the host of a parasite and must pass it on to another player before it devours him. At the same time, players must ensure that the ship's systems do not fall into disrepair, otherwise all players lose the game. Each player also has a gun, which, if used against the host, the game is win for the uninfected players, but if used against a non-host, the parasite wins.
